I think the problem is with the OS. In my home machine(with MS-Windows 7) it is running fine, but in the office machine(with MS-Windows XP SP2) it is giving error. I tried to have a word with my System Admin friend he is bit unaware about the Python environment, and I have a pressing need to solve. I restarted the machine but did not help.
Regards,
Subhabrata.
